Letters Patent No. 96,793, dated November 16, 71869.

IMPROVED BEAM.

The Schedule referred 'to in these Letters P atent and making part of the same.

To all whom 'it may concern Be it known that I, RICHARD J. GATLING, of Indianapolis, in lthe county of Marion,A and State of Indiana, have invented a. new and useful Improvement iu Beams and Girders and I do hereby declare that the following is a full, clear, and exact descrip# tion thereof, which willenable others skilled in the art to make and use ,the same, reference being;` had to the accompanying drawing, forming part of 'this specification, iu whieh- Figure 1 is a cross-section of' a girder, illustrating my invention.

Figures 2 and 3 are cross-sections of slightly-modified forms of the same.

Figure 4 is a' side view of :t portion' of the girder, represented in cross-section in iig. 3.

My invention has for its object to furnish improved girders audbeams for fire-proof buildings and other uses, which sha-ll be so construct-ed that the flooring and laths can be nailed directly to said beams and girders, and which may, at the same time, be constructed with less powerful machinery, and at less expense than when made in the ordinary manner; and

Itcousists in construct-ing the beams andgirders of two iron plates, bolted together, and so formed as to have recesses-in their top and bottom edges, for timbers to rece-ive the nails.

A and B are the iron pla-tes of the girders 'and beams, the central parts or bodies of which are made straight and parallel with each other, and are securely bolted together, as shown in the drawings.

The upper and lower edges of the plates A B are so shaped that when the said plates are bolted together, recesses may be formed inthe two edges of the beams and girders,to receive the wooden strips or timbers C, which should be of suliicient size to receive and hold the nails b v which the flooring and laths are seemed.

The recesses in the edges ol' the beams and gil-ders lmay be wider at their bases and narrower at their outer sides, asshown in iig. 1 or they may be. made he made deep andnarroi', as shown in fig. 3, their particular form being;r innnaterial, so long as they will receive and bold securely timbers of sniiieientsize' to h old the nails.

The timbers C may be secured in place, in the recesses in the edges ofthe beams and girders` by'bolts, if desired or necessary.

Having thus described my invention,

I claim as new, and desire to' secure by Let-ters Herent- An improved bea-m or girder, formed of two iron plates, bolted to each other, and so shaped as to form recesses in one or both edges, to receive timbers, sul sta-ntially as herein shown and described, and for the purpose set forth.

RICHARD J. GATLING.
